Global warming might have something to do with the fact that there are 4 storm systems in existence simultaneously, but we cant say for sure - Scientists

I guess it's a similar situation when someone falls pregnant. No one is sure how it happened, although everyone has a pretty good idea, they're just too...er...[insert expletives here] to admit it.

clipped from green.yahoo.com - Global warming has probably made Hurricane Gustav a bit stronger and wetter, some top scientists said Sunday, but the specific connection between climate change and stronger hurricanes remains an issue of debate. The Atlantic is seeing an increase in storms rated among the strongest. In the past four years, Hurricanes Gustav and Katrina, and six other storms have reached Category 4 or higher with sustained winds of at least 131 mph, according to research at Georgia Tech. Six scientists contacted by The Associated Press on Sunday said this shows some effect of global warming, but they differ on the size of the effect. "We are just seeing a lot more Categories 4 and 5 globally than we have ever seen," said Judith Curry, chairman of Earth and atmospheric sciences at Georgia Tech. "The years 2004, 2005 and 2007 are quite high. We're just seeing more and more."
